DUST-COLLECTO R.

SPECIFICATION forming part of Letters Patent No. 471,272, dated March 22, 1892.

Application filed March 1, 1888- Serial No. 265,807- (No model.)

To whom it may concern.-

Be it known that I, ORVILLE M. MORSE, of Jackson, in the county of Jackson and State of Michigan, have invented new and useful Improvements in Dust-Collectors, of which the following is'a specification.

This invention relatesto a dust-collector which is provided with a tapering or conical separating-chamber in which the dust-laden to air is caused to assume awhirling or rotating motion, whereby the solid particles are driven into the outermost layer of the whirling body of air and massed against the tapering wall of the separating-chamber. Then the solid matter contained in the whirling body of air possesses considerable ponderosity-as, for instance, blocks, shavings, &c. the effect of centrifugal force upon these solid particles is to cause them to recede from the axis of rotation and to move toward the large end of the tapering separating-chamber instead of toward the small end, where the opening for the escape of the solid matter is located.

The object of this invention is to provide the dust-collector with means which overcome this effect of the centrifugal force and compel the large or bulky solid particles to pass to the discharge-opening at the apex of the conical separating-chamber.

My invention consists to that end of the improvements which will be hereinafter fully set forth, and pointed out in the claim.

In the accompanying drawings, Figure 1 is a sectional elevation of my improved dust-collector. Fig. 2 is a horizontal section in line a; as, Fig. 1.

Like letters of reference refer to like parts in both figures.

A represents the conical or tapering sepa rating-chamber of the dust-collector, provided with an inlet-spout for the dust-laden air entering the large end of the separating-chamber tangentially and having in the head Ct at its large end a central opening I) for the escape of the purified air and at its small end or apex an opening 0 for the escape of the solid matter. The air-escape opening I) is provided with a tubular guard d, projecting into the separating-chamber.

e represents a spiral deflector secured to or formed on the inner side of the tapering wall -of the separating-chamber and having the proper pitch to cause the solid matter which is thrown against the under side of this flange 5 5 to move toward the discharge-openin g c at the small end of the separating-chamber. This spiral deflector may be constructed of an angular strip of sheet metal soldered, riveted,

or otherwise secured to the inner surface of 6c the tapering wall, or the latter may be provided with a spiral corrugation, or it may be formed in any other suitable manner.

The dust-laden air entering the tapering chamber tangentially assumes a whirling motion in the same, whereby the solid matter is thrown against the tapering wall. This solid matter encounters in its rotation the spiral flange e, which deflects the matter toward the discharge-opening c at the small end of the tapering chamber and compels the solid matter to escape through the same, while the purifled air escapes through the tube d.

I do not wish to claim in this specification the construction of the separating-chamber itself, nor, broadly, the combination of an internal deflector with the separating-chamber, nor the tubular guard in the air-outlet, as these features are claimed by me in other applications for patent now pending, more particularly Serial No. 197,307, filed March 31, 1886; Serial No. 204,684, filed June 9, 1886; Serial No. 204,686, filed June 9, 1886, and I reserve the right to claim in such applications all patentable matter not specifically claimed herein.

I claim as my invention The combination, with a tapering separating-chamber provided with an inlet-spout for the dust-laden air entering the large end of 0 the chamber tangentially and having an airescape opening at. its large end and an escape-opening for the solid matter at its small end, of a spiral deflector arranged on the inner side of the tapering chamber from 5 the inlet-spout to the discharge-opening for the solid matter, substantially as set forth.

Witness my hand this 27th day of February, 1888.
